Maybe I confused you, sorry, yes I still operate the 950 and only have a maximum capacity of 5.1 through the analog inputs. My question is getting the BDP-83 to take stereo (2 channel source material) and matrix it into the 5.1 channels as my 980H does. Even with the the Oppo Pro Logic II turned on I still get no rear activity with stereo source material whatsoever. Does your BDP-83 work differently and provide rear activity during stereo source material? I do have the 5.1 downmix activated as well.

As a side note, I watched the new Return to Forever Live Blu-ray that sounded (and looked) no less then incredible! The lossless formats do make a stunning difference.
